podman build: --ignorefile is a NOP

[edsantiago]

Basically, the bud --ignore containerignore test from buildah bud.bats

$ tree -A foo-2
foo-2
├── Containerfile
├── ignoreme
├── subdir
│   ├── sub1.txt
│   └── sub2.txt
├── test1.txt
└── test2.txt
$ cat foo-2/Containerfile
FROM quay.io/libpod/alpine:latest
COPY ./ /tmp/
$ cat foo-2/ignoreme
# comment
*
test!
!test2*
subdir
!/sub1*
$ ./bin/podman build -t testignore --ignorefile foo-2/ignoreme foo-2
STEP 1: FROM quay.io/libpod/alpine:latest
STEP 2: COPY ./ /tmp/
STEP 3: COMMIT testignore

If the file is called .dockerignore, it works as expected.

Have you converted this test to a podman system test? I have a PR to fix it, but no test yet, hint hint...

[edsantiago]

I'll write one. Give me an hour please to juggle time for it

[rhatdan]

No problem, I am waiting for the first PR to merge anyways, since this is a follow on.
